VAPO R-GAS APPARATUS.

SPECIFICATION forming part of Letters Patent No. 562,214, dated June 16, 1896. Application filed September 6, 1895. Serial No. 561,710. (No model.)

To all whom it may concern:

Be it known that 1, GEORGE H. BURnows, of Somerville, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Vapor-Gas Apparatus, of which the following` is a specitication.

This invention relates to a vapor gas apparatus in which a current of air is forced into a floating reservoir or holder, from which the air passes to the carbureting-chamber, where it is mixed with the hydrocarbon vapor in said chamber by means of capillary evaporation.

The invention has for its object to provide certain improvements relating to the details of construction of portions of the apparatus; and to this end it consists in the several improvements which I will now proceed to Ldescribe and claim.

Of the accompanying drawings, forming a part of this specification, Figure l represents a longitudinal vertical section of my im proved apparatus. Fig. 2 represents a sectionalized plan view of the same, taken on line 2 2 of Fig. l. Figs. 3 and 4 represent, respectively, sections taken on lines 3 3 and 4 4 of Fig. 2. Fig. 5 represents an enlarged sectional view on line 5 5 of Fig. `2. Figs. 6 and 7 represent sections taken on lines 6 6 and 7 7, respectively, of Fig. 5.

The same letters of reference indicate the same parts in all the figures.

In the drawings, q' represents the carbureting-chamber pivoted at r to lugs s4, affixed to the side walls of the mixing-chamber s. The outer end-of said carbureting-chamber is provided with an air-tight compartment z/, which operates as a float and adapts the chamber q to rise and fall with the liquid and to operate a valve u', secured to the end of the mixing-chamber s and connected with a pipe o to the source of supply, so as to regulate the supply of gasolene or other hydrocarbon liquid in the mixing-chamber s.

In Fig. 5 I have shown onan enlarged scale the means for operating the supply-valve, which consist of a valve u', having a stem w', the outer end of which is provided with a head fy', which is engaged by a` claw y, afliXed to the end of the chamber q'. The valve u' is supported by a nipple t1/3, secured to the of the arrows shown in Fig. 2.

chamber s', through which the stem extends, the outer end yt of the nipple forming the seat for the valve, which will be operated to open or close the passage g5 through the nipple as the supply of gasolene varies in the mixing-chamber s.

The carbureting-chamber q' is provided with compartments b2, formed by sheets of coarse cloth b3, (preferably burlap,) which are secured to the upper inner portion of the carbureting-chamber and extend downwardly therefrom into the gasolene, which is readily absorbed and vaporized by the strips and adapted to be readily mixed with the air which is admitted into the chamber q. The air from the blower (not shown) passes into the chamber q through a pipe b4, one end of which is suitably connected to a coupling b5 loosely fitted upon a pipe h6, which passes through the chamber q, the outer ends resting in the lugs s4 s4, secured to the sides of the mixing-chamber s', said pipe forming a bearing upon which the chamber q' oscillates. The pipe is provided with an opening bl, which admits the air from pipe b4 to the chamber q'. (See Fig. 3.)

The air is conducted through the chamber q' in a sinuous course, space being provided at each end of the chamber for the air to pass around the strips b3 of fabric in the direction At the opposite end of the chamber are openings 138 b9, through which the air and vapor pass into the mixing-chamber s', in which, at one side thereof, is a compartment c2, adapted to contain coarse sawdust and stalks of flagging c3 of the cat-tail (Tg/phat Zatzfoha) variety, which being constituted in layers filled with spongy substance provides an effective conductor and becomes readily impregnated with an additional quantity of vapor.

The chamber c2, containing the flag-stalks and sawdust, is perforated at one end, Fig. 4, to admit the gasolene and vapor to said chamber, and at the opposite end of the latter is a partition which provides a gas-space c4, from which the perfected gas passes through a pipe c5 to the burners.

The sheets b3 are kept saturated with gasolene or other liquid hydrocarbon supplied by the pipe o, connected with the source of supply, and the height of the liquid is governed IOO by the movement of chamber q' through the connection of the latter with the Valve u', as hereinbefore described. An air-pipe c6 connects the chamber s With the top of the supply-tank, so that air displaced by the liquid entering the chamber passes to the tank and replaces the liquid drawn therefrom.

It will be seen by reference to Fig. l that the carbureting-chainber q is of lesser depth at the floating end than at the pivoted end. The object of this construction is to insure the complete absorption of the liquidA in the chamber s by the strips b3, so that in case of the supply of gasolene becoming exhausted, the shorter strips will readily absorb the liquid until the entire amount of the latter in the chamber s' has been absorbed by the strips b3, it being a Well-established fact that the maximum height to which the liquid can be drawn by the strips b3 does not exceed three inches, which fact plainly demonstrates the utility of the shorter strips in the event of a diminished sup ply of gasolene.

I claim- 1. In a carbureter, the combination of an outer casing Whose interior constitutes a mixing-chamber and' contains the charge of hydrocarbon fluid; a carbureting-chamber Within said casing and having a float at one end; a perforated pipe passing through said carbureting-chamber near its end opposite the lioat and supported at its ends on the Walls of the casing, said pipe constituting a support and pivot for the carbmeting-chamber and also a conduit for inlowing air; and an air-supply pipe coupled to said pivot-pipe.

2. In a carbureting apparatus, the combination of a chamber adapted to receive and contain the charge of hydrocarbon fluid; a carbureting-chamber pivotally suspended at one end in said duid-chamber and having a float at the opposite end; a valve controlling inflow of fluid to the chamber said valve having a headed stein Within the latter; and a claw fastened to the Vertical Wall at the pivoted end of the c'arbureting-chamber and embracing the valve-stem back of its head, substantially as and for the purpose described.

In testimony whereof I have signed my'
